Abstract (en)
[origin: WO8201214A1] Thermal treatment apparatus for downhole deployment comprising a combustion stage with an elongated hot wall combustion zone (80) for the substantially complete combustion of the fuel-air mixture and an ignition zone (164) immediately upstream from the combustion zone in which a mixture of atomized liquid fuel and air at or below stoichiometric ratio is ignited; together with a water injection stage (82) immediately downstream from the combustion zone through which essentially particulate free high temperature combustion products flow from the combustion zone and into which water is sprayed. The resulting mixture of steam and combustion products is injected into an oil formation for enhancing the speed and effectiveness of reservoir response due to physical, chemical, and/or thermal stimulation interactions.
